' CHARLES PURRI GTO F PEQUABUOK, CONNEOTiOUT- To all whom it may concern:

I Be it known that LOHARL S PURRINGTON, a citizen of the United States,- residing 'at Pe quabuck, county of Litchfield, State of Connecticut, have invented certain new and use ful Improvements in Blind or Shutter Hinges, of which the following is a specification.

My invention relates to improvementsin blind or shutter hinges; and the objects of my improvement are simplicity and economy in construction and efii'ciency in use, especially with reference to a good hinge that will per-. mit the blind to be readily removed.

- In the accompanying drawings, Figure l is a front elevationof my -hinge. Fig. 2 i'sa plan view of the same. Fig- 3 is as side elevation as viewed from the right h'aud'sideof Fig. 1, In each of. the said threerfigures the hinge is illustrated in its closed position that is, the'position' which it will have in use when the blind is closed. Fig. 4 is a broken side elevation ofthe same as viewed from the lefthand side and with the swinging leaf turned back into a position to bring the blind-approximately at an angle of forty-five degrees to the side of the house.- Fig. 5' is'a sectional plan view of the same with the plunger keyed back and the swinging leaf represented by full lines in position for detachment and by broken lines in the position shown in Fig. 4. Fig.6 is a broken plan view of one of the half-sockets of the house member of my hinge.

The house member'of my hinge is formed of two half-sockets 5 6, havinghinge-lugs 14 at their outer ends, each formed with open main portion of the said sockets are designed to receive and hold the plunger 8 and its spring 9. These half-sockets may beheld together and secured to the building in any ordinary manner; but I prefer to employ lugs 10 on the half-socket 5 to embrace the halfsocket 6 at its outer end and hold the two together, while the other end of the half-socket 5 is provided with a rivet-like stud 11, that enters a perforation 12 in the half-socket 6 and which lug may behammered down to hold the two half-sockets together. The two half-sockets form a cylindrical case adapted to befreceived in a hole made by a suitable boring-tool, and I also prefer to employ a fastening-plate 13, provided with screw-holes and arranged to encircle the case toward its outer end, as shown. A case having hingelugs at its outer end and inclosing a spring pressed plunger for acting on holding-faces Specification of Letters Patent.

'BLI'ND on SHUTTER HINGE.

of a companion hinge member is old and is hereby olisclaimed r In my hinge I make a recess in the edge of' l 1 each of the hinge-lugs '14 on the blind side, so

as to form the key-holding shoulders 15, that face toward-the outer end of the plunger a little to one side thereof, and Iwiden the plun- I get at the'corner adjacent to these shoulders, as shown at the left-hand outer. corner of the plunger in Fig. 5, whereby when the plunger is forced backagainst the power of the spring it may be held in its forced-back position byinsertinga proper key 16, Fig. 5, which key may,be anordina-rycut nail or-similar object;

By-m'aking the key-seat shoulders to one side of a vertical plane extending longitudinall y through the-case andv axis of the hinge I am enabled to pass the key wholly acrossthe front end of the plunger and haveit bear on the case at oppositesid-es of the plunger,

so as to hold the" plunger firmly and closely to its extreme'inward position.

The companion hinge member of my hinge consists of a-hingelug 17, having three holding-fac'es 18, 19, and 20, two pintle-trunnions 21, and a suitable leaf 22 or otherprovi'sion for securing the hinge-lug 17 to the blind. The hinge-lug 17 is of a thickness to be re ceived in the space between the two hingelugs 14 of the companion member, while its trunnions are received and centered in the pintle-receiving pockets'7. The outer [edge of the plunger 8 is rounded in a direction transversely to its broad sides, and the main portions of the holding-faces of the hinge-lug 17 are grooved to fit the said rounded edge,- as shown, The action ofthe spring-plunger on the holding-faces of the hinge-lug 17 confines the trunnions of the said lugs within the pockets 6 of the hinge-lugs 14, while the rounded edge of the plunger and grooved holding-faces assist in holding the parts against accidental displacement. The general action of the plunger and holding-faces is the same' as in prior hinges of this class.

In use both blind-hinges may be of my construction; but only one holding-hinge on a blind is necessary, and thus I prefer to use my hinge as the lower hinge on the blind, in connection with any ordinary loose-joint hinge for the upper hinge of the blind. In case it is desired to remove the blind it is swung open far enough to bring the hinge-lug 17 into the position shown in Fig. 4 and into the position indicated by broken lines in Fig. 5, in which position the plungeris' forced back against the power of its spring. The corner between thehold ing taces. L9 and- 20; is made; a little longer than the corner between the holding-faces 18 and 19, so as to force, the plunger back to a greater extent. When the open space between the shoulders and the confronting corner of the plunger 8; so that a key 16 may be inserted to hold the plunger back, as shown in Fig. 5.. The hinge-tug: ll?- may then be turned into. a position to bringits holding-face 20 substantially parallel. to the. end of the plunger 8,. and then the said face may be moved n p-against the held-back plungen, as shown by the. full lines. in Fig. 5.. The trunnions-Ql of: thesaid hingeAug-l'? wilt of the side openings. so; that the; said lugmay be wholly disconnected; by'rnovi-ng' it, bodily to the right. i

It is apparent. thatsome changesfirom the specific construction. herein disclosed may be; made, and therefore,- L do; not; wish. to, be, un-

derstood. as. limiting myselfi to; the precise;

form of construction; shown and: described, but desire; the liberty to; make Such; changes in. working my invention as: may fairly come; within the spirit and scope of the same.

I claim as my invention-- 1. In a blind. or'shutter hinge,theceranbination of a. case having hinge-lugstopen pintlereceiving pockets, and twokey-seatshoulders formed by open; recesses in the-side edges: of

the saidlugs and located to one sideof a plane extending; vertically along the axis. of. the

hinge and horizontally along the length of the case with aspring-pressedplunger having aflattened' head provided with a laterallyprojecting corner facing the space between :the said key-seat shoulders and correspondplunger is thus forced, back, there is a clear ingly located with reference to the said case andaxi's of the hinge, and a companion hingelugpi voted inthe said lugs of the said case,

for being engaged by the said plunger, the whole being combined and arranged for insetting: asingle: key in the. space between the said twozshouldersand projecting corner, with the; said hey spanning" the space between the saidslmulderswhen. the said plunger and the said; companionv hinge-lug are. in engagement 5 with each other.

then be withdrawn fromthecentering portion: of the pintle-pooket into a position in front 2;, inalblind: or shutterhinge, the combination of the case-having a pain of hinge-lugs and open pintlerrecei-ving pocketsin the confronting facesofthesaid lugs with a springpressed plunger mounted to. slide within the said case and present. its: end face to. the space betweenthesaid' lugs, the, said end face being rounded transversely to. its broad sides, and: a companion. hinge-lughaving trunnions for being received the said pockets and hold-ingrfaoes with grooves thatv are fitted to thesaid rounded enda faceoii the said plunger and? extend along the: edges oi the said holding-faces transversely to the axis of the trunni'ons..
